Facilities and equipment:

As major equipment in the IsoForensics Inc. laboratory, there is a state-of-the-art Thermo Finnigan isotope ratio mass spectrometer (IRMS, model MAT 253). Coupled to the IRMS are peripherals that convert samples into gas, separate the gases, and then introduce them into the IRMS for isotope ratio analysis. The peripherals include:

· A Thermo Scientific high temperature conversion elemental analyzer with zero-blank autosampler that converts samples to hydrogen and carbon monoxide to allow for hydrogen and oxygen stable isotope ratio measurements.

· A Costech elemental analyzer with zero-blank autosampler that converts samples to nitrogen and carbon dioxide to allow for nitrogen and carbon stable isotope ratio measurements.

· A 48-vial GasBench system for collection of carbon dioxide to allow for carbon and oxygen stable isotope ratio measurements.

· A Thermo TRACE gas chromatography system coupled with pyrolysis and combustion furnaces to allow for compound-specific hydrogen or carbon isotope ratio measurements.

The laboratory also houses a Picarro wavelength-scanned cavity ringdown spectroscopy (CRDS) water analyzer (model L1102-i) for the hydrogen and oxygen isotope ratio measurements of liquid samples.

IsoForensics Inc. owns and operates a multicollector ICP-MS (Neptune Plus, Thermo Scientific) that is housed within the Department of Geology & Geophysics at the University of Utah.
